Change is in the air. For what seems like a while now, we've been experiencing adjustments in the way we live, work, and play—some easier to embrace than others. Here at the Bulletin, we're going through some changes, too. All for the better, I think, and I hope you'll agree.

With this issue, we've gone a little shorter, by eight pages. We haven't lost the content you are accustomed to seeing, it's just moved online—and expanded, in some cases. It made sense to trim Bulletin costs by slightly reducing the print version, while offering existing content and then some on the Web.

By visiting the online version of this issue, for example, you'll find a multimedia perspective piece by HHMI investigator Charles Sawyers. In this short audio slideshow, you can listen to Sawyers give his view on the value of translational research and watch him move through a typical work day at Memorial Sloan-Kettering Cancer Center.

One of our feature articles is shorter, with some added extras on the Web. That feature presents the efforts by some universities to give novice teaching assistants, or TAs, a welcome boost in the form of training courses and boot camps. On our website you'll find two audio slideshows—one gives you a glimpse into an MIT training course on diversity, and in the other you get to tag along on a University of Delaware TA's first day as lab instructor.

Other stories are moving online as well, including one of our usual trio of Upfront articles. With this issue, you can go online to read about the recent discoveries of HHMI international research scholar Pascale Cossart on the biology of Listeria infection—and watch a short video of how the bacteria infect a cell.

In coming editions of the Bulletin, we intend to expand our Web extras, in the form of additional stories and interactive multimedia. We hope you'll continue to enjoy our print magazine, and visit the online version to learn even more about HHMI's research and science education efforts. Our goal, as always, is to produce engaging content that both informs and inspires. Drop me a line and let me know how we're doing.
